Next, calculate the net present value of leasing the shuttle bus. Elena has already entered the security deposit amount (cell G3) as the initial investment for leasing and the monthly payments in the range G4:G39. In cell B21, enter a formula that adds the security deposit amount (cell G3) to the result of the NPV function. In the NPV function, use the monthly discount rate (cell B19 ) as the rate of return and the Lease Scenario values for months 136 and the ending value (range G4:G40) as the cash flows for leasing the shuttle bus.|
